1. This is not random sampling. It is systematic sampling
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point and a fixed periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired samplesize.
2. -0.87 is stronger as sign is just for direction but value is strength.
